When I attempt to login to the server, I get through the username and password screen just fine (it rejects bad username/password combinations, and accepts the correct one). However, once I enter my username and password, it stalls for a moment with a message that reads Unable to connect to service.
Error log is:

Rstudio server was working yesterday ,after that i deleted rsession file on /usr/lib/rstudio-server/bin/ accidentally , and I tried loading rstudio server on browser today and it gives error.
I uninstalled R and other related components form ubuntu 16.04 server and then reinstalled again.
